Personal Computer Systems

Posted by BrianRS 947 days ago (http://hubpages.com)
It is a pretty well known fact that the personal computer has advanced at an exponential rate over the last 30 years or so. It was the IBM released in 1981 that was considered the first with a PC label. Check out its operating specifications:

* Monitor - monochrome (optional colour monitor)
* Hard Drive - N/A
* Floppy Drive - 2 x 160K
* Memory - 16k to 256K
* Serial Interface - RS232 (x2)
* Speed 4.77MHz
* Operating System (OS) -DOS 1.0 16-bit (could run on BASIC without an OS)

It was during the 70's that I was first introduced to a computer when I was studying at college learning how to program in the 'Basic' language. Back in those days your code had to be absolutely perfect and a missed 'dot' or 'colon' anywhere in your code would result in the nightmare 'syntax error' which told you there was a problem but absolutely nothing about what or where the problem was.
